Have you ever thought, “I wish I could take a year off and just travel around the word?” Well, three lucky American teenagers were able to do just that. The teens — two males and one female — got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person’s actions. They realized that each of them can make a difference.
【小題1】These teenagers went on the journey around the world      .

A．to experience the most serous environmental problems on the earth
B．to bring the kindness of America to the other parts of the world
C．to go on sightseeing around the world
D．to call on more teenagers to join Earthwatch Institute
【小題2】What’s TRUE about their journey?
A. They had to pay for their journey on their own expense.
B, They often had to move from one hotel to another.
C. They had to take great pains to collect environmental information.
D. They received a warm welcome every time they arrived at a new place.
【小題3】It can be inferred that Earthwatch Institute could be          .
A. an international university that takes in students from all over the world
B. a TV station that makes programmes on the beautiful scenery of the earth
C. a travel agency that organizes adventure trips specially for school children

Google is testing its newest high-tech device, Google Glass. Most of the technologies for Google Glass are already available on smart phones. Google has taken those same technologies and added them to eyeglass frames（眼鏡架）. The company describes the glasses as wearable computers that would change the way people view others and the world.
"Google Glass is a tiny computer that sits in a lightweight frame, and rests neatly above your eye and it makes exploring and sharing the world around you a lot easier,” said Chris Dale, the Senior Manager of Communications for Google Glass.
The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through WIFI, a smartphone, or a tablet computer. You can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame.
Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass. "I thought this is something I definitely need for my classroom and hopefully for my personal life too."
The Professor's Google Glass looks like a pair bright orange glasses, without the actual glass. But there's a tiny rectangular（長方形的）glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class.
But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy.
John Simpson is the director of the privacy project at Consumer Watchdog.
"It is going to allow people to come in and spy on you and record that, without you knowing what is going on."
Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured（捕捉）a man getting arrested after a fight. He shared the video on You Tube.
Also some are concerned about the use of facial recognition（面部識(shí)別）technology on Google Glass. But Google says it will not approve the use of such applications. The Internet company says it is still testing its new device, and it hopes to make Google Glass available to the public by early next year.
【小題1】The technologies Google has made use of for Google Glass are______.

A．completely new
B．mostly already in use for smartphones
C．high-tech but out-of-date
D．a(chǎn)ll old
【小題2】Which of the following is not true about Google Glass?
A．It’s a very small computer.
B．It’s very light in weight.
C．Everyone can buy it now.
D．It can be used for teaching by school teachers.
【小題3】While cycling, the Professor has used the Glass to ______.
A．record video and chat B．send emails
C．teach a class D．spy on others
【小題4】What can be inferred from the passage？
A．Google has done what it can to protect people’s privacy.
B．Google Glass may be used for bad purposes.
C．Most people feel worried about the use of the Glass.
D．Google Glass is more useful than smartphones.

Europe is now the biggest market for organic food in the world, having grown by 25 percent a year over the past 10 years. Denmark’s agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 60 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.
So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides(殺蟲劑). Organic farmers rely on many methods — such as crop rotation (農(nóng)作物的輪作) and the use of resistant（有抵抗力的）varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.
Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture stated that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.
【小題1】The first paragraph mainly tells us _________.

A．organic farming has been performed only in Europe over the past 10 years.
B．governments of European countries have cared less about organic farming.
C．organic farming isn’t so popular as expected.
D．European countries need organic food more than the other countries in the world.
【小題2】The underlined words “compensate for” in the second paragraph probably mean “_________”.
A．a(chǎn)rgue forB．care for
C．make up forD．pay for
【小題3】 What can we know about organic farming?
A．It refers to farming with natural materials, instead of chemical fertilizers.
B．It refers to farming with chemical fertilizers rather than natural fertilizers.
C．It refers to farming with soil rather than any other thing.
D．It refers to growing crops with man-made fertilizers and pesticides.
【小題4】According to the third paragraph, _________.
A．organic farming is safer than traditional farming for the environment.
B．the idea that organic farming is safer has not been proven by science.
C．organic farming is accepted by the UK’s House of Commons committee.
D．organic farming is preferred to traditional farming.
【小題5】Which of the following is TRUE, according to the passage?
A．The UK’s agriculture minister is an organic farmer.
B．Organic farming is popular with young people.
C．Farmers try every means to improve the organic sales system.
D．Ninety-three percent of British shoppers don’t buy organic products.

All of us eat every day, but most of us don’t understand nutrition(營養(yǎng)). How much do you know about good nutrition? Are the following statements true or false?
1. People who don’t eat meat can stay healthy.
True. As long as people eat enough milk, eggs and meat alternates(替代物), they can get enough protein.
2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.
False. The difference depends more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can lose a large quantity of vitamins.
3. Food eaten between meals can be just as good for health as food eaten at regular meals.
True. Nutritional value depends on what types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.
4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.
True. It’s widely believed that extra vitamins provide more energy. But taking more than the baby needs doesn’t make it function better, just as overfilling your gas tank doesn’t make your car run better.
5. Natural vitamins are better supplements(補(bǔ)充)for the diet than synthetic vitamins.
False. There is no difference. A vitamin has the same properties(性質(zhì))and specific chemical structure whether made in a laboratory or taken from plant or animal parts.
6. Older people need the same amount of vitamins as younger people.
True. Older people need the same quantity of vitamins as younger people although they need fewer calories. Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.
7. Food grown in poor soil is lower in vitamins than food grown in rich sold.
False. The vitamins in our foods are made by the plants themselves. They don’t come from the soil.
However, the minerals in a plant depend on the minerals in the soil.
If you have answered these questions correctly, you can say you know much about food and nutrition by today’s standards. But remember that nutrition is a growing science and that may be aged as new information is obtained.
【小題1】The main purpose of the passage is to           .

A．list today’s standards of some food and nutrition
B．introduce what should be eaten and what not
C．explain what is helpful to your health and what is not
D．test our nutrition IQ by judging the problems listed

Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窩)-either recorded or real-may even prevent elephants from damaging farmer's crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today,  Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.
【小題1】We know from the passage that elephants may be frightened of         .

A．loud noises B．some crops 
C．video cameras D．a(chǎn)ngry bees 
【小題2】As mentioned in the passage, Lucy
A．works by herself in Africa 
B．needs to test more elephant groups 
C．has stopped elephants eating crops 
D．has got farmers to set up beehives on their farms 
【小題3】Why did Lucy throw a stone into a wild beehive?
A．To record the sound of bees. 
B．To make a video of elephants. 
C．To see if elephants would run away. 
D．To find out more about the behavior of bees. 
【小題4】Which of the following is true according to the passage?
A．Young elephants ignore African honeybees. 
B．Waterfalls can make elephants stay in one place. 
C．Elephants do not go near trees with bees living in them.  
D．Farmers do not allow Lucy to conduct tests in their fields.

DNA left at a crime scene could be used in the future to build up a picture of an offender’s face, it was revealed tonight.
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突變) that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.
【小題1】The underlined word “mugshots” in the second paragraph most probably means _________.

A．different faces B．characteristics C．pictures of faces D．genders
【小題2】What can be inferred from the passage?
A. DNA has been used to build up a picture of an offender’s face.
B. It may be much easier to catch criminals with the help of DNA.
C. In all, 20 genes had “significant effects” on facial appearance.
D. One gene can affect more than one part of your face.
【小題3】According to Professor Mark Shriver, we know_________.
A．they can merely match to an individual or identify an individual
B．there is a possibility of going from DNA to a face
C．DNA could be used to produce a rough image of an offender’s face
D．this technology is more reliable than computer-generated “e-fits”
【小題4】What is the most possible title of the passage?
A．Creating a data bank of DNA
B．Recognizing the DNA of criminals
C．Predicting the location of offence using DNA
D．Building image of offender’s face from DNA
